Kernel-4.18.0-80.el8_adi,axi-spi-engine

Analog Devices AXI SPI Engine controller Device Tree Bindings

Required properties:

  • compatible : Must be “adi,axi-spi-engine-1.00.a””
  • reg : Physical base address and size of the register map.
  • interrupts : Property with a value describing the interrupt
            number.
    
  • clock-names : List of input clock names - “s_axi_aclk”, “spi_clk”
  • clocks : Clock phandles and specifiers (See clock bindings for
            details on clock-names and clocks).
    
  • #address-cells : Must be <1>
  • #size-cells : Must be <0>

Optional subnodes:
Subnodes are use to represent the SPI slave devices connected to the SPI
master. They follow the generic SPI bindings as outlined in spi-bus.txt.

Example:

spi@@44a00000 {
    compatible = "adi,axi-spi-engine-1.00.a";
    reg = <0x44a00000 0x1000>;
    interrupts = <0 56 4>;
    clocks = <&clkc 15 &clkc 15>;
    clock-names = "s_axi_aclk", "spi_clk";

    #address-cells = <1>;
    #size-cells = <0>;

    /* SPI devices */
};
